This must be a simple thing to do but I am having problems. I have a series of data that represent points in 3D space, which essentially form a deformed sphere. I thought that if I attached to each point a constant data value, say '1', then all I would have to do is to use IsoSurface to form a surface from all the points with the data value '1', .i.e. all points
Thus my data set of 'n' points looks like n lines of : x y x 1 .... etc In my case the number of points is formed from sampling a sphere at 3 deg intervals in theta and phi, yielding 120 x 60 = 7200 points. Isosurface needs connections, so read the data set in using the data importer as a 120x60 regular grid with two fields. The first field I changed to 'locations', as a 3-vetcor field, and the second I changed to 'data' as a scalar field. I then hocked up the IMPORT module to the ISOSURFACE module and IMAGE. But I don't get anything out. Is there something obvious I am doing wrong. Any help would be appreciated. Wyn
